IMPROVEMENT IN VENTILATORS FOR R-AILROADCARS.

Specification forming part of Letters Patent No. 127,559, dated J unc 4, 1872.

-road cars, by Which fresh air from Without can be introduced into the car and foul air discharged therefrom Whilethe car is moving in either direction.

Description of the Accompanying Drawing.

Figure 1 is a vertical central section in the plane of the line of motion ofthe car, indicated by the dotted line a b, Fig. 2. Fig. 2 is a partial front elevation and a partial vertical section at right angles to the former, the line of section being indicated by the dotted lines c d, Fig. 1. Fig. 3 is a small detached view,

yshowing a modification of the lower part of one of the shields or air-deflectors.

General Description.

A is the outside casin g of the structure, which is erected upon the roof of a railroad cal-with its mouths BB presented fore and aft, so as to catch and collect the wind inone or the other, according to the direction `of motion of the car. The flange C, near the foot of the structure, rests upon the oar-roof, and, besides serving as a base, keeps the drip from penetrating the opening at which enter the downcast and up-cast pipes E F. The mouths B B are covered with wire-cloth so as to exclude dust and flyin g bodies, While admitting pure air. D D are the down-cast ducts to carry the air to the interior of the car. F is the up-cast pipe, Within which the stove-pipe may be applied in cold Weather, so that the smoke and gases of the stove will be discharged with the vitiated air. G is the cap or cowl upon the flue, and is detachable.

In Warm Weather, when the stove is disused, the structure described is used merely as a ventilator, when the down-cast pipes carry fresh air into the car and the up-cast pipe receives the foul air therefrom.

Should it be desired to use for the downcast the Wholel interior space except that oc'cupied by the pipe F, the shields may be shaped as in Fig. 3, so that theyv may lap upon the smoke-pipe F.

The structure is preferably made of galvanized sheet-iron.

O mim What I claim as new is- The car-ventilator or jack herein described, consisting of the bell-shaped months B B', down-cast ducts D D', and up-cast pipe F, the latter being placed concentrically Within the conducting-neck of the down-cast ducts, and all arranged to operate substantially as hercin set forth.
